Preface

This is the second edition of CSA W55.3, Certification of companies for resistance welding of steel and aluminum. It supersedes the first edition, published in 1965 under the title Resistance Welding Qualification Code for Fabricators of Structural Members Used in Buildings.

This edition includes the following changes:

1. broadening of the scope to include both steel and aluminum, as well as non-structural applications;

2. alignment with CSA W47.1, including introduction of three divisions of certification; and

3. editing of the terminology to bring this Standard in line with other CSA Standards and with the terms

   and definitions of the American Welding Society.

   This Standard stipulates the minimum requirements that a company must meet and adhere to in order to obtain and maintain certification in the area of resistance welding. Certification is granted by the Canadian Welding Bureau, the administrative body of this Standard. Certification indicates that, consistent with the requirements of the division in which the company is certified, the company has the organization, personnel, welding procedures, equipment, and process control system required to produce satisfactory welds and welded assemblies using resistance welding processes.

   This Standard was prepared by the Technical Committee on Certification of Companies for the Welding of Steel and Aluminum, under the jurisdiction of the Strategic Steering Committee on Welding and Structural Metals, and has been formally approved by the Technical Committee.

   Notes:

   1. Use of the singular does not exclude the plural (and vice versa) when the sense allows.

   2. Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

   3. This publication was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.

   4. CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.

   5. All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.

      Requests for interpretation should

      1. define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

      2. provide an explanation of circumstances surrounding the actual field condition; and

      3. be phrased where possible to permit a specific “yes” or “no” answer.

Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSA’s periodical Info Update, which is available on the CSA Web site at www.csa.ca.

Certification of companies for resistance welding of steel and aluminum

Certification of companies for resistance welding of steel and aluminum

1. Scope

   
   

   1.1

   This Standard specifies requirements for the certification of companies engaged in resistance welding of steel and aluminum.

   
   

   1.2

   This Standard specifies requirements for

   1. the qualification of personnel;

   2. the qualification of welding procedures; and

   3. process control procedures.

   
   

   1.3

   This Standard does not address safety issues associated with welding and welding practices. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

   Note: CAN/CSA-W117.2 addresses safety in welding.

   
   

   1.4

   In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

   
   

2. Reference publications

This Standard refers to the following publications, and where such reference is made, it shall be to the edition listed below, including all amendments published thereto.
